Bug 244604

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
What I was doing when the application crashed:
Whenever I try to login as a user with KDE since my updates this morning, I get this segfault. Windows work fine, but no panels or plasmoids are loaded. Even KWin compositing works just fine, as well as alt-tab and window borders.

The crash can be reproduced every time.

 -- Backtrace:
Application: Рабочее пространство Plasma (kdeinit4), signal: Segmentation fault
